We are going to carry on our systematic method to diagnosing a pool heater by seeking at how to proceed control heater in the event the light inside the manage pad to the top rated of your Sta-Rite pool and spa heater that may be labeled “service heater” is lit. (We are going to move forward while using the assumption that you choose to know every thing from section one.) This time you must clear away the perimeters with the heater in advance of disconnecting electric power towards the heater so that you can study the codes to the board connected into the topside. After getting rid of the sides, you will see the big topside that is definitely nonetheless connected to the heater. Beneath the topside is a steel panel that keeps the topside in position. Under this panel you will discover two locking pins (cotter pins). Carefully eliminate the 2 pins and shop them somewhere protected right up until reassembly. Gently get rid of the best and switch it the wrong way up. You will see a light-weight lit on the board you are seeking at whenever you transform the topside around. The sunshine will likely be next to a code that is certainly written on the board.

The very first code that you're going to see to the left side of the board is going to be PS. This is the code for the tension change. We protected the stress change in section 1. If this mild is lit go back to phase one particular and evaluation that segment. If vital adhere to the recommendations to exchange the tension change.

Another code you will see on the board is HLS. In the event you have a controller to the technique you will need to bypass it presently. You must carefully disconnect the power from your heater. After you are absolutely sure the electric power is disconnected, you have got to come across and open the high-voltage cabinet. This cupboard is usually a metallic box in the course of the heater. Should you be looking at the cabinet, there exists normally a screw around the prime ideal aspect. Loosen the screw and the doorway will swing down toward you. You'll need for being extremely watchful when doing work in this particular box and only do so any time you are absolutely sure that the energy into the heater is OFF.

You must bypass the firewall safety interface. To accomplish this you will require a quick wire with stab-tab connectors. For those who have a controller and it was appropriately installed the wire can have been still left within the box with the tech who put in the controller. If not you need to make this jumper wire. At this time search in your owner's manual to track down the two right pins to hook up with. Should you possess a controller or are working with a fireman's switch this is when your control really should be linked. When you possess a controller and it can be not linked listed here, it could be the source of one's issues and both possess a certified tech correct the trouble or suitable it oneself.

You need to be cautious to not set the jumper wire over the electric power terminals otherwise you will ruin your heater by burning up the electronic process. Make use of your guide to find where the fireman's change is supposed to become attached and carefully attach your jumper amongst these terminals. If you now turn on the facility and the heater operates with none complications, your problem lies inside the controller or maybe the wiring visiting the controller. You have got to difficulty shoot this technique.

In case you still have the same challenge with the heater. (“service heater” gentle arrives on), depart the jumper set up and confirm which the pump is on which you might have very good h2o circulation. Make sure once again with your meter that the strain switch is just not biking. It ought to go through to be a dead small. (See section one particular) With fantastic h2o stream verified as well as the “service heater” gentle on, your trouble may very well be among the thermo-regulators from the safety technique.
